Lord Nelson was an East Indiaman, launched in late 1799, sailing for the East India Company. She made five voyages, of which she completed four. On her second voyage the French privateer Bellone captured her, but the Royal Navy recaptured her within about two weeks. On her fifth voyage, Lord Nelson foundered in 1808 with the loss of all aboard.

East Indiaman was a general name for any sailing ship operating under charter or licence to any of the East India trading companies of the major European trading powers of the 17th through the 19th centuries. The term is used to refer to vessels belonging to the Austrian, Danish, Dutch, English, French, Portuguese or Swedish companies.
